Modular tuner and method for manufacturing the same

Abstract

Disclosed herein are a modular tuner and a method for manufacturing the same. The modular tuner includes a metallic casing, a tuner adaptor and a plurality of metallic elastic pieces. The metallic casing has an opening, and the tuner adaptor has a metallic outer surface. The plurality of metallic elastic pieces and the metallic casing are integrally formed by stamping followed by bending, and the metallic elastic pieces extend outwardly from the edge of the opening of the metallic casing and respectively interfere with the metallic outer surface of the tuner adaptor.

Description

RELATED APPLICATIONS[0001]This application claims priority to Taiwanese Patent Application No. TW102129681, filed Aug. 19, 2013, the entirety of which is herein incorporated by reference.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates to a tuner; more particularly, a modular tuner and a method for manufacturing the same.[0004]2. Description of Related Art[0005]Tuners include the FM / AM tuner comprised in certain main stations and television tuners. A television tuner (also known as high frequency tuner) is an important component in the receiving terminal end of a television. Common television tuners complete the process of receiving, amplifying, strobing, frequency conversion and demodulation in an analog way; if any distortion or loss of fidelity occurs during said process, the quality of the received image and accompanying sound would be degraded.[0006]Referring to FIG. 1; while assembling the tuner, the adaptor 120 is inserted into the iron casing 110 and th...

AI Technical Summary

Benefits of technology

The patent text discusses a new invention related to a tuner, which is used in electronic devices. The invention addresses the issue of parasitic capacitance, which can cause problems with the performance of the tuner. The invention uses a new method to improve the structure of the tuner and decrease the negative effects of parasitic capacitance. The invention also includes a flexible way to connect and assemble the tuner adaptor and the metallic casing, which reduces manufacturing costs. Overall, the invention improves the performance and reduces the complexity of tuners used in electronic devices.

Problems solved by technology

When the tuner is under a high frequency, a potential difference exists between the two parallel polar plates, and hence the parasitic capacitance is generated in the gaps, which will cause problems associated with excessive contact resistance, and accordingly, the tuner may not be in compliance with the electromagnetic compatibility (EMC) regulations.

On the other hand, the iron casing 110 and adaptor 120 of the tuner are connected via riveting connection, which renders the unpacking of the tuner quite difficult.

Also, in the case where the adaptor type of the tuner shall be altered, it is requisite to build a new mold, thereby increasing the manufacturing cost.

In view of the foregoing, there exist problems and disadvantages in the existing products that await further improvement.

However, those skilled in the art sought vainly for a solution.
